What is Norton’s Dome and how does it reveal indeterminism in Newtonian physics?
That had produced so much fuss was somehow shocking. This literature has been teetering on the edge of nonsense for a hundred years.
Professor John Norton of the University of Pittsburgh has spent decades systematically dismantling sacred assumptions of physics. Norton's Dome, for instance, demonstrates fundamental indeterminism in Newtonian physics itself. Now you may be thinking of quantum uncertainty, but I'm talking about classical physics, which is breaking down in terms of unique predictivity. Beyond determinism, Norton critiques notions of causation itself. Physicists routinely invoke causal language, but what if causation isn't fundamental? Even further, Norton's critique extends to thermodynamics. Landauer's principle, for instance, has guided decades of research into computing limits, and some even use it as the physical basis of Wheeler's it from bit.
Norton demonstrates this principle misunderstands thermodynamics and entropy, both of which we talk about in extensive detail. We then cap it off with Einstein's contributions to old quantum theory and Einstein's disagreements with the new quantum theory. A special thank you to The Economist for sponsoring this video. I thought that The Economist was just something CEOs read to stay up to date on world trends, and that's true. However, that's not only true. What I've found more than useful is their coverage of math, of physics, of philosophy, of Especially how something is perceived by countries and how it impacts markets. Among weekly global affairs magazines, The Economist is praised for its non-partisan reporting and being fact-driven.
This is something that's extremely important to me. It's something that I appreciate. I personally love their coverage of other topics that aren't just news-based as well. For instance, The Economist had an interview with some of the people behind Deep Seek, the weak Deep Seek. Launched. No one else had that. The Economist has a fantastic article on the recent DESI dark energy data, and it surpasses, in my opinion, Scientific Americans' coverage. The Economist's commitment to rigorous journalism means that you get a clear picture of the world's most significant developments. It covers culture, finance, and economics, business, international affairs, Britain, of course, Europe, the Middle East. East, Africa, China, Asia, the Americas, and yes, the USA.
Whether it's the latest in scientific innovation or the shifting landscape of global politics, The Economist provides comprehensive coverage that goes beyond the headlines. If you're passionate about expanding your knowledge and gaining a deeper understanding of the forces that shape our world, I highly recommend subscribing to The Economist. It's an investment into your intellectual growth, one that you won't regret. I don't regret it. As a listener of To, you get a special 20% off discount.

Thanks for tuning in, and now back to the exploration of the mysteries of the universe. John Norton. All right. Professor John Norton, you're a legend in the physics scene and the philosophy of physics scene, so it's an honor to be with you here. Oh thank you very much. It's very kind of you. You're known for Norton's Dome, for indeterminism and systematizing material induction, your views on thought experiments, the history of Einstein. and disproving Landauer's principle. We'll attempt to get to all of these today. Now before we get to these, let's pick one. Norton's Dome. Why don't you tell me how did you arrive at that construction? What were you trying to show? Were you trying to be contentious? Were you trying to disprove a colleague?
Did something just not make sense? Like walk me through leading to Norton's Dome.
It was uh actually completely trivial and that it produced so much fuss was somehow shocking. So here's here's the background.
